ScubaSwap

Buying pre-owned scuba equipment is the ultimate "life hack" for divers looking to save money, but it requires a keen eye for detail. Whether you’re hunting for a used BCD, a second-hand regulator, or a reliable dive computer, here is a checklist to ensure your next "swap" is a success. 1. Demand the Service History For life-support equipment like scuba regulators, a low price tag often hides a lack of maintenance. Always ask for the last service date. If it hasn't been oxygen-cleaned or bench-tested in over a year, factor the $100–$150 service fee into your offer. 2. Inspect for "Invisible" Wear Check rubber hoses for "dry rot" (tiny cracks when bent) and look for green oxidation (verdigris) on brass fittings. These are signs that the gear wasn't rinsed properly with fresh water after salt-water dives. 3. Stick to Major Brands Focus on brands like Scubapro, Mares, Aqualung, and Cressi. The reason isn't just quality—it's parts availability. Most local dive shops can easily source service kits for these manufacturers, whereas "off-brand" gear might end up being unserviceable. 4. Test the "Hold" on BCDs If you’re buying a used BCD, inflate it until the over-pressure valve pops, then let it sit for 20 minutes. If it loses any firmness, there’s a leak in the bladder or a faulty dump valve.
